Agents that act in reality.
Payments, delivery, trading, alerts, and voice in one API — built for AI agents that need to move beyond chat.
One call can start a payment, book a delivery, fetch a quote, or route a voice flow. SDKs in Python · TypeScript · Go.
Connect any agent over the Model Context Protocol. Claude · GPT · in-house models.
Talk to the agent in plain Korean. The sentence becomes a tracked, confirmable action.
Drag the canvas — the signal responds
One call, accountable action.
Five primitives you can ship with. Each one is a working product surface, not a demo wrapper — composed from the same SDK.
Payments
Tokenize a card and settle fast. Toss · Kakao · Naver Pay · Payco — 9 PGs behind one contract.
Delivery
From pickup to last mile. One call issues the waybill, then live location streams back.
Trading
Quotes, executions, and positions in one schema for Korea and global markets. Paper trading first; live trading behind staged auth.
Voice
18 Korean-tuned voices with sub-320 ms first-token latency. Routes straight into IVR when the flow calls for it.
Brand Monitoring
Detect brand mentions as they happen, classify sentiment and context, then alert Slack or email. Negative incidents escalate immediately.

How extn.ai earns trust.
We build the boring, necessary layer between AI intent and real-world execution: clean schemas, confirmation flows, audit trails, and fewer surprises in production.
One layer for real-world actions
Payment, delivery, alerts, trading, and checks stay separate under the hood, but agents can use them through one consistent action layer.
Signals worth acting on
Track keywords across news, social, blogs, and communities with monitoring tuned for relevance, not raw volume.
Human handoff, by design
When reality needs judgment, the context moves with the task so a human can step in without starting over.
Pricing that stays out of the way
Start small, add volume when the action proves itself
